9.6 will be fine. Thats what I'm running and I have no problems. My machine shop said the same thing because they are dinosours...and have no idea about fuel injection and what you can do...heck, stock is 9.4 to 1, I wish I would have gone with a thinner gasket to get it closer to 10 to 1, but oh well. Go with a bigger cam! That cam is too small...dont go with something as big as my cam as you'll lose too much low end...but that ZZ4 cam is just a little too girly.
